The SECUNORM PROFI25 is aptly named. "PROFI" because this knife really does behave professionally. Whatever the situation, whatever the cutting material. And the "25" is in reference to its impressive blade extension of 25 mm, with which even 3-ply cardboard can be conquered. And just like all other members of the PROFI family, SECUNORM PROFI25 features automatic blade retraction.
